Disturbing Levels of Lead and Cadmium Found in Protein Powders, Study Reveals
Over-the-counter protein powders, often marketed as health supplements, may contain alarming levels of heavy metals like lead and cadmium, according to a recent investigation.The highest concentrations were found in plant-based, organic, and chocolate-flavored products, raising concerns about the safety of these widely consumed dietary aids.
The Occupational Safety and Health Administration.
The findings come from a report released by the Clean Label Project, a nonprofit organization dedicated to promoting transparency in food labeling. Jaclyn bowen, the executive director of the Clean Label Project, revealed that “on average, organic protein powders had three times more lead and twice the amount of cadmium compared to non-organic products.”
The study tested 134 protein powder products,with 70% of samples showing detectable levels of lead and 74% containing cadmium. Plant-based powders were particularly problematic, with 75% testing positive for lead. Organic versions of these powders were found to have 4.8 times more cadmium than their non-organic counterparts.

Sign up for Dark Chocolate and Protein Powders: Hidden Heavy Metal Risks in Health Foods
Dark chocolate, frequently enough celebrated for its rich content of flavonoids, antioxidants, and beneficial minerals, has recently come under scrutiny for containing high levels of heavy metals. A July 2024 study published in Frontiers in Nutrition revealed that 43% of six dozen dark chocolate products exceeded California’s Proposition 65’s maximum allowable dose level for lead, set at 0.5 parts per million. this alarming finding raises concerns about the safety of a product frequently enough marketed as a health food. Similarly,protein powders,particularly plant-based varieties,have been found to contain elevated levels of heavy metals.A recent report highlighted that plant-based protein powders, such as those made from soy, rice, and peas, contained three times more lead than whey-based products. Whey, a byproduct of cheesemaking, appears to be a safer choice in this regard. Heavy metals like lead and cadmium are naturally present in the earth’s crust, but their levels can spike due to human activities. Plants absorb these metals from the soil, and contamination can worsen in areas affected by mining, industrial waste, and the use of certain pesticides and fertilizers. This explains why plant-based protein powders and dark chocolate, both derived from crops, are particularly vulnerable. “heavy metal contamination is a global food safety problem,” said Bowen, a researcher involved in the study. “These contaminants are basically everywhere, including in things that are being represented as health foods.” The report also identified chocolate flavoring as a significant source of contamination in protein powders. Chocolate-flavored protein powders were found to contain four times more lead and up to 110 times more cadmium than their vanilla-flavored counterparts. this finding underscores the risks associated with chocolate-based products, even in powdered form. The Council for Responsible Nutrition, an industry association representing supplement manufacturers, criticized the report for lacking transparency. In an email to CNN, the council stated that the study did not provide sufficient details about the criteria used for contamination thresholds or how products were selected. | Product | Contaminant | Levels Compared to Standards | While heavy metal contamination is a widespread issue, consumers can take steps to minimize exposure: The presence of heavy metals in foods like dark chocolate and protein powders highlights the need for stricter regulations and better transparency in the food industry. As Bowen aptly put it, “These contaminants are everywhere,” reminding us that even health foods are not immune to global environmental challenges.For more information on the health benefits of flavonoids, check out this CNN article. to explore the full study on dark chocolate contamination, visit Frontiers in Nutrition. Stay informed, stay safe, and make mindful choices about the foods you consume. A recent investigation by the Clean Label Project has raised concerns about the safety of protein powders, a staple in many fitness enthusiasts’ diets. The study, which tested 160 products from 70 top-selling brands, found traces of harmful contaminants, including heavy metals and bisphenols. However,the organization has chosen not to disclose the specific brands tested,citing fairness and consistency as the primary reasons. “We do not disclose the names of companies we test in order to maintain fairness and consistency and to avoid potential conflicts of interest,” said Jackie bowen, executive director of the Clean Label Project. The protein powder samples were sent to an independent certified laboratory, where they underwent nearly 36,000 individual tests for 258 different contaminants. These included heavy metals like lead and cadmium, bisphenols (BPA and BPS), phthalates, and perfluoroalkyl and polyfluoroalkyl substances (PFAS). However,the 2024 report focused only on levels of lead,cadmium,bisphenol A (BPA),and bisphenol S (BPS). Data on other contaminants will be released in a later update, according to bowen. The findings have sparked debate within the supplement industry. Andrea Wong, senior vice president of scientific and regulatory affairs at the Council for Responsible nutrition (CRN), emphasized the importance of transparency in such studies. “Without such clarity, consumers and industry stakeholders cannot fully evaluate the validity of the claims,” Wong said. She also pointed out that modern analytical techniques can detect trace levels of naturally occurring elements, such as heavy metals, which are often present in soil, air, and water. “These trace levels are often well below established safety thresholds set by federal agencies like the Food and Drug Administration (FDA) and the Environmental Protection Agency (EPA),” Wong added. the study highlights the need for greater transparency and stricter quality control in the production of protein powders. While trace amounts of contaminants may not always exceed safety thresholds, their presence raises questions about long-term exposure and potential health risks. | Contaminant | Details | As consumers await further updates from the Clean Label Project, experts recommend staying informed about the products they use. Checking for third-party certifications and researching brand transparency can help ensure safer choices. For more information on the health effects of bisphenol A (BPA), visit the National Institute of Environmental Health Sciences. The debate over protein powder safety is far from over, but this study serves as a crucial reminder of the importance of rigorous testing and transparency in the supplement industry.— Bisphenols, a group of chemicals widely used in plastics and resins, have long been under scrutiny for their potential health risks.Studies have linked these hormone disruptors to a range of alarming health issues, from fetal abnormalities and low birth weight to brain and behavior disorders in infants and children. In adults, exposure to bisphenols has been associated with type 2 diabetes, heart disease, erectile dysfunction, cancer, and even a 49% higher risk of early death within a decade. Bisphenol A (BPA), one of the most well-known bisphenols, was once a staple in the production of baby bottles, sippy cups, and infant formula containers. However, a wave of concern from parents led to widespread boycotts of these products over a decade ago. This public outcry forced manufacturers to rethink their use of BPA, but the chemical’s legacy continues to haunt us. In 2018, the Clean Label Project conducted an investigation into protein powders, revealing high levels of bisphenols in many products. Fast forward to 2024, and the findings are more encouraging.According to the latest report, only three out of 160 protein powders tested contained BPA or its cousin, Bisphenol S (BPS). This is a significant enhancement from 2018, when 55% of the products tested showed detectable levels of these harmful chemicals.“We found BPA and BPS in only three of 160 protein powders, compared to 55% of the products we tested in 2018,” said Bowen, a representative from the Clean Label Project. While bisphenols remain a concern, the clean Label Project’s 2024 report also highlights the presence of heavy metals in consumer products. Researchers compared levels of lead and cadmium in protein powders to the safety thresholds established by California’s Proposition 65, a law designed to protect consumers from exposure to harmful chemicals. The findings underscore the importance of rigorous testing and transparency in the food and beverage industry. | Issue | Findings | The findings from the Clean Label Project serve as a reminder of the importance of being vigilant about the products we consume. While the reduction in bisphenol levels in protein powders is a positive step, consumers should continue to advocate for transparency and safety in the food industry. Look for products that have been independently tested and certified by organizations like the Clean Label Project. By staying informed and making conscious choices, we can protect ourselves and our families from the hidden dangers of bisphenols and other harmful chemicals. — A recent report by the Clean Label Project has raised concerns about the safety of protein powders, revealing that nearly half of the products tested exceeded California’s Proposition 65 lead limits. The findings highlight the need for consumers to be vigilant about the products they incorporate into their diets. The study analyzed 160 protein powder samples in 2024, with alarming results. 47% of the products tested surpassed the Prop 65 regulatory guidelines, which are among the strictest in the U.S.for industrial environmental contaminants. Shockingly, 21% of the powders contained lead levels twice as high as the Prop 65 limit. The data also revealed significant differences between product types: “Prop 65 is arguably the most progressive law in the land when it comes to industrial environmental contaminants,” said Bowen, a spokesperson for the Clean Label project. “They have very clear pass-fail criteria that is typically much stricter than federal agencies in the US.” | Protein Powder Type | Percentage Exceeding Prop 65 Lead Limit | While the findings are concerning, experts emphasize that protein powders can still be part of a healthy lifestyle—if chosen wisely. “It’s not necessary to stop using protein powders as part of a healthy lifestyle,” Bowen said. “But it does help to shop smart.” For those on a plant-based diet, pea protein powders appear to have the lowest levels of heavy metals.For others, whey-based or egg-based, vanilla-flavored protein powders are recommended, as they showed the least contamination. Bowen also advises consumers to reach out to brands directly to inquire about contaminant levels. “Ask questions, demand answers,” she said. “The topic of heavy metals isn’t going away.” The presence of heavy metals in protein powders underscores the importance of transparency in the health and wellness industry. As consumers become more aware of potential risks, they are increasingly demanding accountability from manufacturers. For now, the key takeaway is clear: shop smart, ask questions, and stay informed. By doing so, consumers can continue to enjoy the benefits of protein powders while minimizing potential health risks. — | Contaminant | Details | |——————————|—————————————————————————————–| | Lead | 47% of protein powders tested contained lead levels above California’s safety limits. | | Cadmium | 33% of products exceeded cadmium thresholds set by Proposition 65.| | Arsenic | 21% of protein powders had arsenic levels higher than the recommended safety limit. | | Mercury | 6% of products tested showed mercury levels above safety standards. | California’s Proposition 65, also known as the Safe Drinking Water and Toxic Enforcement Act, requires businesses to provide warnings about significant exposures to chemicals that cause cancer, birth defects, or other reproductive harm. The law sets strict safety thresholds for heavy metals like lead, cadmium, arsenic, and mercury, which are known to pose serious health risks even at low levels of exposure. the Clean label Project’s findings have prompted calls for greater accountability within the protein powder industry.Consumers are encouraged to: While protein powders are frequently enough marketed as essential for fitness and health, the presence of harmful contaminants raises significant concerns.The Clean Label Project’s report highlights the need for continuous monitoring and enhancement in product safety standards to protect consumers from long-term health risks. — Stay informed and make safer choices.
